Abstract (en)
A tip (24) on which a plurality of protrusions (31) are formed in a regular pattern is provided to a horn (23) side of an ultrasonic bonding device (21). Each of the protrusions (31) is shaped as a square pyramid having four side surfaces (31a, 31b, 31c, 31d) and a flat top surface (31e). An apex angle (α) formed by two mutually opposite side surfaces is greater than 90°, e.g., is 120°. When two separators (1) of a battery cell are joined together, a force with which the separators (1) adhere to the protrusions (31) is weak, and the separators (1) do not adhere to the horn (23).
